[Openais] corosync trunk - fix ring buffer implementation in logsys

[Steven Dake]

The current logsys does not use a file backed mapping for its circular 
buffer.  It requires a circular buffer managed by the memory manager. 
This patch fixes that problem.

This patch also fixes the error handling of the writing of the logsys 
fplay buffer to be more correct.
